stick of the loom as a cushion therefor, and

means for ositivel oeratin from said device, a brake member or binder onthe shuttle box of the lay, whereby the shuttle will be stopped and heldon the end of its throw at the proper place in said box.

It consists also of means for adjusting the pressure on said member orhinder.

It consist also of details of construction as will be hereinafterdescribed and pointed out in the claims. l

The invention is satisfactorily illustrated in the accompanying drawing,but the important instrumentalities thereof may be varied, as long as.they areincluded in the scope of .the claims. 1

Figure 1 represents a side elevation of a shuttle check embodying myinvention. Fig. 2 represents a partial bottom plan view and partialhorizontal sect-ion thereof. Fig. 3 represents a vertical section of aportion on the line zr--m Fig. .1, on an enlarged-scale. Fig. 4represents a perspective view of a detached portion of the device andFig. 5 represents a partial side elevation and a partial verticalsection thereof, the members in Fig. 4: being separated.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 designates the shuttle box of a loom, thesame being supported on the lay of the loom as usual, and having thepicker stick 2 entering the same from below, as well known. To theunderside of said box is secured the bracket 3 on which is pivotallymounted the arm 4 which depends from its axis on the bracket 3 and has aheel 5 between which and said bracket is interposed the spring 6, thesame being adapted tobecompressed and contracted when said arm isengaged'by the picker stick, whereby when said arm is released ofsaidpicker stick said springreturns the formerto its normal position.The depending member of the arm at is directly in the path of thepicker-stick 2.

freely with the side of said arm is the bar 7 which is formed of rigidmaterial and extends longitudinally along the box 1 and is connectedwith the crank arm 8, the latter being secured to the lower end of therocker or-rock shaft 9, which is mounted in vertical directioninbearings 10 on the side of the box 1. Projecting laterally from theshaft 9 is thetongue'or brake operating vmember 11 whose free end isadjacent to the'binder or brake member 12 which occua pies an opening inthe side of the box 1, and 1n the present instance has an end1nt'egrally connected with said side,wherebysaid member 1s resilient 1nlts nature, it being noticed that said member is adapted to be forcedinto the boxl by the action of the tongue 11 and be placed in the pathof a side of the shuttle that is projected into said box by the actionof a picker as usual in such cases.

V The bar 7 is adjustably connected with the crank arm 8 so as to adjustthedegree of oscillation of the latter and the axial end of said crankarm 8 is formed with the serrated collar 13 which is adapted to engagewith the serrated. collar 14 on the adjacent end of the rock shaft 9 bywhich provision the degree of rocking motion of said shaft 9 may beadjusted, whereby more or less pressure may be exerted by the tongue 11on the brake member, and the extent of inward motion of the latter maybe adjusted, said pressure being adapted to be exerted on the shuttlethat enters the box 1, so that said shuttle will be brought to a gradualstop at the proper time in its box.

When the collars 14: and 13 are separated,

the rock shaft 9 may be rotated and so set or adjusted to the requiredextent. When .this is accomplished, the said collars are broughttogether when their teeth interlock, and the bolt 15 passed through thecrankarm and said collarsinto the rock shaft is tightened, thusretainingsaid collars connected as one, and securing the crank arm with the rockshaft. I

The bearings-10 are formed each of separate members which are connectedby the screw 17 which is passed through said mem- I bers holding theportion of the rock shaft '9 within said members, said portion having aswell or .coll-ar 18v which acts as a shoulder assis ing. retaining t rok sha i p s tion, nd us e ame 1 9 ret te tr e in its bearing. Theformation of the bearings of separate members or sections admit of theready displacement and replacement of the shaft from said bearingswithout necessarily disturbing the other connections of said shaft. Thespring 6 is sustained on the bolt 19 which is fitted in the heel 5 ofthe arm 4 and seated in the adjacent portion of the bracket, said springbeing interposed between said bracket and heel as has been stated.

The operation is as follows :The parts are shown in their normalposition on the left end of a lay, and the shuttle thrown by the righthand picker not shown, whereby it enters the left box. Then, the lefthand picker receives the impact of the shuttle whereby the picker stitchis thrust against the arm 4 which I now denominate as a check for thepicker, and as the picker stick is capable of a slight motion to theleft, the arm 4 is thrown back by the same resisted by the spring 6,thus providing a cushion or buffer for the picker stick whichresiliently receives the impact of the picker stick and gradually checksthe motions of the same to its end. Simultaneously therewith, the bar 7is drawn back with said arm 4, thus rotating the crank arm 8 and therock shaft 9, whereby the tongue 11 forces in the brake member 12 andcauses the latter to contact somewhat resiliently with the side of theshuttle and serves to slow the motions of the latter, and resilientlystop the same in the box 1 at the proper time. Then as the left handpicker stick has completed its motion, and is ready to move the shuttleto the right, the arm 4 is relieved of said picker stick, when thespring 6 is permitted to expand, which it does, restoring the arm 4 toits normal position, moving the bar 7 to the right, and operating thecrank arm 8, the rock shaft 9, and tongue 11 in such manner that saidtongue is removed from the brake member 12, when the latter resumes itsnormal position and withdraws from the shuttle just when the left handpicker is ready to throw the shuttle to the right, the shuttle thenbeing in no wise held or controlled by the brake member and so may beoperated immediately to the right.

The inner sides of the separate members or sections of the bearings 10are tongued and grooved so that said sides interlock and so firmlyconnect the sections or members when tightened by the screws 17 Theswells or collars 18 are on the exterior of said sections respectivelyabove and below the same as shoulders as hereinbefore stated, saidshoulders being adapted -to rotate on the bearings, they avoidingreduced necks on the rock shaft which weaken the latter, while on thecontrary strengthening said rock shaft and allowing the openings in thehearings to remain truly circular without deepening said openings toreceive the swells, thus preserving the strength of the bearings.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is
